CATALINA_HOME ignored and reset by catalina.sh

           Summary: CATALINA_HOME ignored and reset by catalina.sh
           Product: Tomcat 4
           Version: 4.1.9
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: ide@nlm.nih.gov


catalina.sh header documentation claims you can set CATALINA_HOME but
actually catalina.sh will ignore (reset) whatever you specify and
jam the value to the location of catalina.sh.

This was not always true -- Revision 1.20 (from 4.0.1) actually let
you set this and it wouldn't step on the value.

You can fix this by adding back in the logic: 	
	if [ -z "$CATALINA_HOME" ] ; then
around the setting of it.

Or, (IMO a worse alternative), if you really don't want to 
provide this hook into the script, then document that CATALINA_ROOT
is no longer an environment variable of interest -- and document that
the actual location of catalina.sh must be identical to CATALINA_ROOT.
(I don't like this because I use symbolic links to break out the
various components of CATALINA_ROOT and I don't want catalina.sh 
assuming that everything is physically in the same directory.)

Also, depending on how you resolve this problem, it is imperative that
you resolve http://nagoya.apache.org/bugzilla/showvotes.cgi?bug_id=12065

By the way, the addition of CATALINA_BASE is a good step in the right direction.

In additional nice step would be to separate CATALINA_BASE_CONFIG
(for instance configuration files -- ie, readonly files) 
from CATALINA_BASE_OUTPUT 
(for instance log, work, and temp files, ie, writeable files)
